In most battles, sieges are often the most time-consuming part of a war. It is not uncommon for the besieging side to retreat due to low morale and heavy casualties, thus entering a long siege period. Siege, unsurprisingly, is the most advantageous of all siege methods for the besieging side, and it only takes a few insignificant grains and grass to besiege from spring to late autumn...... The more people there are in a city, the more advantageous it is to besiege the city, because the food and grass consumed by the people will have a huge impact on the enemy army in the city.

It takes a year and a half to capture a city by the simplest means than it is to be strewn with corpses. The huge amount of food and grass and the huge manpower and the pension of the wounded and wounded soldiers are insignificant.

The large-scale use of catapults in the Yan army greatly changed this phenomenon, giving the besieging army the opportunity to cross the walls and demoralize the defenders. On the way south of the Yan army, under the bombardment of stone artillery, a more effective combat method was smashed in addition to the strong attack and siege - that is, a huge number of stone cannons were assembled to bombard a single city wall, supplemented by a salvo of bows and crossbows to hit the morale of the defenders, so as to form an absolute advantage on one side, and then use a large group of foot soldiers to board the undefended city, and directly enter the street battle with the enemy after grabbing the urn city.

This method of warfare has made great contributions to the Yan clan's southward expansion, but once it encounters a city with a very wide moat, it can only find another way. Just like this Guangling City, because there are many waters on all sides, the moat is more than 30 zhang wide, and the stone cannons erected between the sediment depressions on the riverside cannot bombard the city, but it may be difficult for the besieging soldiers to climb because of the accumulation of rubble, so that people cannot attack the city.

In normal times, the Yan clan could only besiege a city like Guangling, and there was nothing else they could do, because any forcible siege would mean that the head of the city would cause the Yan soldiers to be killed or wounded. Today, however, the situation is different, and it is no longer meaningless for the city to allow the soldiers to be killed or wounded at the head of the city...... In this case, any general should have the courage to give it a go.

The scouts who passed through the siege through the secret passage in the moat and entered the camp in the southwest of the city returned to the camp, reported the situation of the camp in the city to Xu Huang, and brought back the token of Chen Deng, the Taishou of Guangling. The fighting in the city continued, and Xu Huang looked at the city with a frown. The dense defenders were relying on the city to give the Yan army who had attacked the city a strong counterattack, and their army could not break through the defenders to gain a foothold on the city walls in a short time.

This is just the city of urns, and the siege is far from over, but the sun has already faded.

"Send two more captains to attack Xiweng City."

Xu Huang's Chinese army was also located in the southwest corner, a direction that allowed him to take into account the siege of the city in both the west and south directions. Outside the east moat is Tian Yu's camp, and the light leather armor and short-range bows and crossbows of the sailors are not suitable for the siege of the city, so they just pile up earthwork outside the city to build a watchtower, so as to observe the movement in the city at night, in addition to strengthening the strength of the drawbridge with strong bows and crossbows.

Outside the city wall in the north, there is no Chen Bu army village and army, Xu Huang left a gap for the war-weary soldiers and people in the city to flee, and at the same time, there are dozens of warships in the water outside the city to block the river, and there are Huaxiong's subordinates on land to block the road...... If most of Yuan's army fled from the north gate, Xiliangxiao would make them suffer.

The main attacking force of this war is the main force of Xu Huang's subordinates, with the waning sun, Xu Huang's camp lit a bonfire, and on the watchtower without light, Xu Huang raised his eyes to look east. There is only one Guangling City, but there are two battlefields in Xu Huang's heart, one is the west city wall and the south city wall that his subordinates attack, and the other is the street battle between Chen Deng's Guangling County soldiers and Yuan's in the city.

Although the two battlefields are in different directions, they face the same enemy, and thus complement each other. If the defenders of the city wall are dealt a major blow, it will inevitably make the reserve army in the city strain to relieve the pressure on Chen Deng, and Chen Deng's troops will be able to seize the city gate from the rear to give back to the besieging army; The same situation is the same for Chen Deng's troops, if the Yuan reserve army is defeated in the street battle in the city, the defenders of the city will also send troops down the city, so that the city head will be empty and Xu Huang's troops will bring an opportunity to take advantage of...... Whichever side of the battle will be victorious.

But the same is that Xu Huangbu also has to bear more risks because of this. It was dark, and if the battle continued, it would be a night battle, but his men could not return because of the friendly forces in the city, and they still fought in the city. This is a road of no return, once the Chen Dengbu in the city is defeated, the huge casualties suffered by storming the upper city will turn into unprovoked losses.

As the sun grew dark, the pontoon bridges erected by the ships on the moat covered the river, and with the reinforcement of the two captains along the ladder to attack the city, in the blink of an eye, the besieging army had paid more than a thousand casualties, and more soldiers climbed the city head under the western city wall, and the besieging army had a slight foothold.

An hour after they began their siege, Xu Huang was rewarded, and the two Qubu soldiers successfully held the two ends of the urn city on the western city wall, making way for the subsequent siege army to ascend the city.

The city of Urn has been captured!

Immediately after, a huge shouting and killing sound broke out in the southwest of the city, and Xu Huang's heart jumped violently...... Chen Dengbu's storming of the street battle has come to fruition!

Yuan's reserve army was not strong for the long-standing and warlike pirates of Xuezhou's subordinates, on the one hand, the county soldiers formed by the stragglers and brave pirates, holding armor that could not be called elite; On the one hand, the Yuan reserve army, which was formed by hastily assembled veterans who were good at fighting and people who had no experience in participating in the war, was almost defeated by the Xue Zhou department, which left the camp to protect at the beginning of the battle.

But as the war continued, the Yuan reserve army, which was complex and uneven in the level of soldiers, showed fatigue, and those of them who wore armor but could not be called sergeants at all showed timidity, dragging the hind legs of the Yuan old soldiers, when the Yuan old soldiers' troops were consumed in the street battles, fear spread among them, but the Haikou was stimulated to fight more and more bravely after seeing the blood of the robe, followed by the Yuan reserve army in the city!

In the shouting of killing, Xue Zhou led the troops to rush to the west city gate, and the two teams of sergeants were shot over by the arrows thrown from the city before they arrived at the city gate, and then hundreds of people blocked the city gate, pushing the boulder rolling wood in the city gate hole, trying to block the city gate.

Seeing this scene, Xue Zhou immediately ordered the herald to gallop to the south city gate, and sent a message to Chen Deng to grab the south city gate, and he himself led the troops to kill the enemy army at the city gate, where he wanted to attract the attention of the enemy army for the Yan army besieging the city.

The situation is getting better and better for the Yuan defenders, Guangling City is like a broken clay pot, leaking everywhere but there are only a few tiles, and they don't know where to plug it.

Under the dark night sky, I don't know where on the battlefield came out first to exclaim, and then the fighting between the two sides stopped invariably...... Guangling Chengguan Temple, it's on fire!
